Apart from CPU and Memory, anther speed bottle neck is storage. There are 3 types of storage to select in the cloud services – harddisk (slowest), ssd (fast), nvme (very fast).
Assuming a server rack setup from 32 disks budget about $300 – $400 each on a raid 6 array, which cost about $10k for all those disks.
We select the following, at the time of writing Western digital Ultrastar HC320 8TB on Amazon AU is $319,
Samsung 870 evo 2tb ssd on Centrecom is $363
and Samsung 970 evo plus 2tb nvme on Centrecom is $369.
We have the following table, if you setup for a rack for 32 disks in raid 6 array. hdd is $4.2c/GB, ssd is $19.4c/GB, nvme is $19.7c/GB for a 5 years hardware life cycle.
| Disk type | brand + model | size | **total | total$ | *$ /GB |
|---|---|---|---|---|---|
| hdd | WD Ultrastar | 8TB | 240TB | $10208 | 0.042 |
| ssd | 870 evo | 2TB | 60TB | $11616 | 0.194 |
| nvme | 970 evo plus | 2TB | 60TB | $11808 | 0.197 |
| Disk Type | Life Time | $/GB/Y | $/GB/M | $/GB/D |
|---|---|---|---|---|
| HDD | 5yr / 2750tbw | 0.0084 | 0.0007 | 0.00003 |
| SSD | 5yr / 1200tbw | 0.0388 | 0.0033 | 0.00011 |
| NVME | 5yr / 1200tbw | 0.0394 | 0.0033 | 0.00011 |
The table shows a fair deal, if a hosting ISP or a cloud ISP provide the above $/GB pricing or less than this consumer price. Lastly, How much are you paying for cloud storage now?
